Add .NET Controls to SolidWorks using an Add-in Example (C#)

This example shows how to add .NET controls to SolidWorks' FeatureManager, PropertyManager, Task Pane, and model view using a C# add-in.

//----------------------------------------------------------------------------

// Preconditions:

// 1. In Microsoft Visual Studio 2008 or later, create a project using

//    Other Languages > Visual C# > My Templates > SwCSharpAddin.

// 2. Name the project DotNetControlsDemo.

// 3. Copy and paste this into SwAddin.cs of your C# add-in.

//    Copy and paste this into UserPMPage.cs.

//    Copy and paste this into PMPHandler.cs.

// 4. Select Debug in the Solution Configurations dropdown in the toolbar.

// 5. Select Project > DotNetControlsDemo Properties.

// 6. On the Application tab, ensure that the Target Framework is

//    .NET Framework 3.0.

// 7. On the Debug tab select Start external program and type in the

//    pathname of your SolidWorks executable.

// 8. Save the project.

// 9. In Solution Explorer add the following .NET Framework 3.0 references:

//    PresentationCore.dll

//    PresentationFramework.dll

//    UIAutomationProvider.dll

//    WindowsBase.dll

//    WindowsFormsIntegration.dll

// 10. Add a Windows Presentation Foundation User Control to the project:

//     a. In Solution Explorer, right-click the project and select

//         Add > User Control.

//     b. In Name type WPFControl.xaml.

//     c. Select the User Control (WPF) template.

//     d. Click Add.

//     e. Copy and paste this into WPFControl.xaml.

//     f. Copy and paste this into WPFControl.xaml.cs.

// 11. Add a Windows Forms User Control to the project:

//     a. In Solution Explorer, right-click the project and select

//        Add > User Control.

//     b. In Name type UserControl1.cs.

//     c. Click Add.

//     d. Copy and paste this into UserControl1.Designer.cs.

// 12. Create a Windows Form:

//     a. In Solution Explorer, right-click the project and select

//        Add > Windows Form.

//     b. In Name type Form1.cs.

//     c. Copy and paste this into Form1.Designer.cs.     

// 13. Save the project.

//

// Postconditions:

// 1. In SolidWorks, select DotNetControlsDemo > WinFormInTaskPane.

//    A new tab with .NET controls appears in the Task Pane.

// 2. Select DotNetControlsDemo > UserControlInModelView.

//    .NET User Control1 tab appears below the model view.

// 3. Select DotNetControlsDemo > WPFInModelView.

//    .NET WPF Control tab appears below the model view.

// 4. Select DotNetControlsDemo > WinFormInFeatureMgr.

//    A new design tree appears in a split window of FeatureManager.

// 5. Select DotNetControlsDemo > Show PMP.

//    Click OK in three dialog boxes.

//    A new tab with .NET controls appears in PropertyManager.
